Pendulum saw

The saw is hung on a swinging arm, sometimes with a counterbalance weight.

A swing saw is also sometimes called a cut-off trim saw in a mill for cutting right angle to the direction of the wood grain.

A swing saw is a very dangerous tool, even with a blade guard.

Early models were driven by a belt, usually made of leather, that was powered by a water mill or later a steam engine.

Today the power source is an electric motor or a gas engine Swing saws are used to carve ice blocks from the frozen Songhua River for the Harbin International Ice and Snow Sculpture Festival each year.
